Ferrite Magnets By Ma'anshan Baiyun Co., Ltd

Our range of Ferrite Magnets or Ceramic magnets are manufactured from a composite powder containing Iron oxide and Barium or Strontium oxide. It is most widely used because of its low cost, high-energy, good electric insulation and excellent resistance to demagnetization. The most common type of ceramic magnets are anisotropic strontium, anisotropic barium and isotropic barium magnet.
Ferrite Magnets suit a wide range of applications due to their low cost. They are readily available in arc segments, blocks, rings and discs. Principal applications are DC motors, loudspeakers, reed switch operation, magnetic separator assemblies and general holding devices such as pot magnets. The un-magnetized blocks are machined using diamond cutting machines to match customer's exact specification.
Ferrite has an excellent resistance to demagnetization and can be magnetized before or after assembly without danger of losing any performance. It can be used in operating temperatures ranging from -40A C to + 250A C. However it does have a poor temperature coefficient losing approximately 0.2% of remanence per degree C when heated above zero.
There are two manufacturing process for Ferrite Magnets: Dry Process & Wet Process. By dry process, can produce isotropic & anisotropic magnets, by wet process, only anisotropic magnets can be produced.
